2 Claims. (Cl. 12042.12)

This invention relates generally to Writing instruments and is moreparticularly concerned with new and useful improvements particularlyrelated to fountain pens.

A primary object of invention is to provide a novel fountain penconstruction including a pen point assembly providing pen pointsaffording width graduation of a line being inscribed, and furtherincluding independent pen points which are supplied from independent inkreservoirs wherein different color inks are afforded in a singlefountain pen.

A further object of invention in conformance with that set forth residesin a novel pen point assembly constructed from segmental block elementswhich cooperate to define the independent pen point assemblies.

Further objects of invention reside in the novel combination andstructural details of the novel fountain pen and pen point assembly.

And yet another object of invention in conformance with that set forthresides in a novel fountain pen which is readily and economicallymanufactured, easily used, and highly satisfactory and practical for thepurpose intended.

These together with other objects and advantages which will subsequentlybecome apparent reside in the details of construction and operation asmore fully hereinafter described and claimed, reference being had to theaccompanying drawing forming a part hereof, wherein like numerals referto like parts throughout, and in which: Figure l is a perspective viewof the novel fountain Figure 2 is an enlarged vertical sectional viewtaken substantially on line 22 of Figure 1; 7

Figures 3, 4, and are transverse sectional views taken substantially onlines 3-3, 4-4, and 5-5, respectively, of Figure 2, Figure 5 beingsubstantially enlarged;

Figure 6 is an enlarged perspective view of the novel pen point assemblyincorporated in the invention;

Figure 7 is an exploded perspective View of the pen point assembly ofFigure 6; and

Figure 8 is an enlarged bottom plan view of the novel pen point assemblylooking from line 8--8 of Figure 6.

Referring to the drawing in detail, the novel fountain pen is indicatedgenerally at, 10 and includes a barrel memberlZ and a pen point assemblyindicated generally at 14.

The barrel or body member 12 is open at both ends and is constructed ofany suitable material, plastic lending itself to mass productionmethods, and has extending longitudinally therewithin a partition wall16 integral with a transverse partition 18 at one of the open ends, theother open end being received in a suitable groove portion 20 of a plugelement 22, said plug element 22 being disposed about the innerperiphery of the other end of the body member 12. The partition Wall 16defines within the body member separate ink reservoir compartments 24and 26 which may contain different colored inks such as blue and red,for example. The plug element 22 has extending transversely therethroughbore portions 28 and 30 which respectively communicate with the inkreservoir compartments 24 and 26, each of said bore portions 28 and 30incorporating therein a refill valve assembly for filling saidcompartments with ink.

The valve assemblies of the bore portions 28 and 30 are indicatedgenerally at 32 and include a spherical valve element 34 engageable witha suitable valve seat portion 36 at one end of the bore portions, seebore portion 28, said valve element 34 being engaged by one end of acompression spring element 38, the other end of which being inengagement with a suitable retaining screw element 40 threadedlyreceived within the other end of said bore portions, said retainingscrew 40 having a transverse aperture portion 42 permitting the passageof ink therethrough when the valve element 34 is depressed, the inkreservoir compartments being filled by means of a suitable eye dropper,for example. The other end of the body member 12 is externally threadedand receives thereon a suitable closure cap 44. j

The partition wall 18 has extending therethrough transverse apertureportions 46 and 48 in communication with reservoir compartments 24 and26, and the one end of the body member 12 terminates in a peripheralflange portion 50, said flange portion receiving therein the portionadjacent one end of a suitably conformed pen point assembly support core52 which includes on its one end tubular sleeve elements 54 and 56 whichare respectively received within the transverse aperture portions 46 and48, see Figure 2. The tubular sleeve elements 54 and 56 communicate withinternal ink passage portions 58 and 66, respectively, which extendlongitudinally in spaced relationship within the support core 52. Theportion adjacent the end of the support core 52 remote from the bodymember 12 is conically shaped about the outer periphery, and included inthe end thereof is a recess portion 62 communicating with the inkpassage portions 58 and 60. The recess portion 62 may have a circularcross section and removably received therein a conforming portion 64adjacent one end of the pen point assembly 14. Circurnposed about theflange portion 50 of the body member 12 and the support core 52 is asuitably conformed ferrule element 66, the free end portion of whichterminating intermediately of the tapering or conical portion 68adjacent the other end of the pen point assembly providing means forprotecting a users fingers from accidental contact with the ink on thepen point assembly.

The pen point assembly comprises segmental block elements '72 and 74arranged in face to face abutting relation, the abutting faces of theblock elements having cooperating longitudinally extending grooveportions 76 and 78, Figure 7, which define together a longitudinal bore.portion 70. The block element 72 has longitudinab ly extending sideportions 80 and 82 which will have juxtaposed thereon longitudinallyextending side portions 84 and 86, respectively, of the block element74, and when the block elementsare juxtaposed in their assembledrelationship as shown in Figure 6, the engaged faces thereof will defineink passage portions 88 and 90 extending radially of the central boreportion 70, see Figure 6, which accordingly receive ink from the boreportion 58 in the support core, it being noted in Figure 2 that the boreportion 78 of the pen point assembly is in communication therewith. Thesegmental block elements 72 and 74 respectively include about theirouter peripheries alignable groove portions 92 and 94 which receivetherein a resilient retaining ring element 96 which will be circumposedabout said segmental block elements for maintaining the pen pointassembly in its assembled condition. The block elements convergeadjacent the mat- Patented Nov. 5, 1957 ing sides 80 and 84, and 82 and86 including at their. lower end pen nib portions 98 and 100, seeFigures 6 and 7 accordingly providing plural pen points 102 and 104, seeFigure-8; said pen points being supplied by the same inkreservoircompartment but being so dimensioned to afford means whereby-differentwidths of lines may be inscribed with the writing instrument.Accordingly, the user of the writing instrument merely has to rotate thebody member 12- in his hand for utilizing either one or the other of theplural pen points of the fountain pen.

Extending longitudinally in spaced relationship from the longitudinallyextending groove portions 76 of the segmental block element 72 is alongitudinally extending groove 106, see Figure 7, which receivestherein a longitudinall-y extending tapered strip element 108 beingretained in overlying relationship relative thereto by means of theresilient ring element 96 engaging a transverse notch portion 110' insaid strip element. The groove portion 106 .combines with the stripelement for defining on the outer periphery of the block element 72 alongitudinally extending ink conducting duct as clearly seen in Figure5. The lower end portion of the segmental block element 72 terminatesadjacent the lower end of the longitudinally extending groove portion106 in a laterally extending nib portion 112 defining a pen pointassembly 114. The groove portion 106 is in communication with the inkpassage portion 60 and accordingly receives a supply of ink contained inthe reservoir compartment 26, this pen point portion being radiallydisposed relative to the longitudinally extending bore portion 70 of thepen point assembly. Inasmuch as the pen will be disposed in an angularrelationship relative to a writing surface, each of the pen points maybe used independent of the other without the ink supply available toeach of the pen points becoming mixed.

As seen in Figure 1 the ferrule portion 66 may have inscribed thereon asuitable indicia 114 and 116 for indicating the respective colorsavailable from a given side of the fountain pen.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling Within the scope of the appended claims.
